This paper examines the intertwined issues of memory and forgetting, focusing particularly on the question of precisely how, and by what social mechanisms, forgetting is accomplished. I discuss how collective and individual forms of forgetting are central to Bourdieu's notion of the habitus, commenting that the habitus is a living paradox, foreclosing (unimagined perhaps because unimaginable) possibilities and opening others only when moments of improvised reflection intervene. Moreover, the systems of the habitus enact a forgetting of the strange, the marginal, the in-between, and even the singular and the autobiographical. I explore these issues through the juxtaposition of formalized, collective Samburu (Kenyan pastoralists) memory forms and the illicit sexual practices that underworld them.
